my 2c worth; they will not buy back PXUPA because it would be much easier for them to simply stop paying the interest - therefore the debt is no problem.
where would they get the cash to buy back the PXU?
if they got rid of the PXU it would likely make them a t/o target as debt reduced, why would they want that ?
better to wait for a t/o offer l would suggest.
the reset is not for a year, so why would they rush to sort that problem out - in a year they will either be bankrupt or sailing along more smoothly.
